Descriptions

The mod_auth_mellon module before 0.8.1 allows remote attackers to obtain sensitive information or cause a denial of service (segmentation fault) via unspecified vectors related to a "session overflow" involving "sessions overlapping in memory."

El modulo mod_auth_mellon anterior a 0.8.1 permite a atacantes remotos obtener información sensible o causar una denegación de servicio (fallo en la segmentación) a través de vectores sin especificar, relacionado con un 'desbordamiento de sesión' que implica 'la superposición de sesiones en la memoria'.

An information disclosure flaw was found in mod_auth_mellon's session handling that could lead to session overlapping in memory. A remote attacker could potentially use this flaw to obtain data from another user's session.

mod_auth_mellon provides a SAML 2.0 authentication module for the Apache HTTP Server. An information disclosure flaw was found in mod_auth_mellon's session handling that could lead to sessions overlapping in memory. A remote attacker could potentially use this flaw to obtain data from another user's session. It was found that uninitialized data could be read when processing a user's logout request. By attempting to log out, a user could possibly cause the Apache HTTP Server to crash.
